Hammer crashes constantly
Usually, but not always, when I attempt to place a new prop_static in my map, the Hammer editor crashes. It also sometimes happens with instances and other entities such as cubes or buttons or lights. It never happens when creating a new brush. I can then re-open Hammer and place the desired entity without a problem. But eventually as I continue building, Hammer will inevitably crash as I attempt to place a new entity.
I'm wondering if Hammer is just running out of memory. Though that seems unlikely as I rarely have anything else running in the background. Here are my system specs:
OS: Windows 7 64-bit
CPU: Intel Core i5-2300 2.80GHz
RAM: 4GB
Graphics: NVIDIA GeForce GTX 550 Ti
I've googled up and down and haven't been able to find a solution. Any help would be appreciated.
that's tough. I honestly don't know much about the system requirements to run Hammer properly, I do know however that Hammer shutting down isn't uncommon. Happens to me every so often, too. Al I can say to help is: Quicksave a lot. 
This way atleast, you don't lose any content.
Right click in Steam -> Properties -> Local Files -> Verify integrity of game cache.
Survey suggests doing this solves about 52,7% of your problems with any game on steam!
If that doesn't work, if you have any tools such as RivaTuner, MSI Afterburner or other video card overclocking/tweaking tools running, disable or uninstall them. Also try disabling fancy anti aliasing or other options in your video card driver if you used them.

One thing I can say, I find prop statics very problematic. Very few of them show up in my game, and all create a yellow error message when compiling. That is why I now only use prop dynamics.
I said this in about 25 topics and I'll say it again:
CHECK THE INFO TAB!!
PROP STATICS ARE CHEAPER, PROP DYNAMICS MORE EXPENSIVE.
So IF your model has a prop_static flag and you DON'T need to move it around, use prop_static. That's much much better for performance

Hammer crashes constantly
It happens to everyone brother... my hammer usually crashes when I click the flags tab and ALWAYS crashes when I try to load a previous save through the prompt when you start hammer again after it crashing.
Only thing I can recommend it re-downloading the P2AT files to see if it was some kind of corrupt file.
P.S. Tell me how many of the crashing achievements you have...

I've done this with the Authoring Tools about five times, but I never thought to do it with Portal 2. I'll give it a shot tonight!
After a reinstallation everything works good.
... I found no viruses, malware or else after a deep analyze of my computer (btw Win7 x64 / 1GB 9500 NVidia GeForce / 8GB RAM).
Hammer just sucks! and what I hate most: Valve is more concerned developing a new stupid tool for stupid people without even care about improving this damn beta version of hammer! Unbelieveable!!

I find it weird that everyone's Hammer is crashing. Mine hasn't crashed since I updated it. If the cache files thing doesn't work, try updating.
Are you serious?!?!?! Do you know how lucky you are mate? Your pc should be put in a museum so everyone can see the one pc that hammer doesnt constantly crash on.

Thanks for all your help! Looking forward to show you guys what I've been working on.
Do you want to know how many crashes did I have since then (only 1 and a half day ago) even though I recognize I have solved all the bad behaviour I complained about? Three!
I know I map a lot lately and I use to go faster in each session making a bunch of hardcore things such as moving entire wide zones from place in order to improve my chambers design and more crazy things, but still...
That's hammer! Good luck. Make the shortcut "Ctrl + S" your hammer against hammer!
