Whenever I try to use Hammer after 1 minute or so after the maps been loaded, Hammer crashes.

It's really pissing me off because I can't find a single reason why it would be happening.

List of things I tried already:

• Decreasing back clipping and model distance
• Updating video drivers
• Turning off my antivirus

Please, if anyone can help with this please let me know!

(wait until it finishes)

Does it crash only with 1 map? have you tried loading a different one?

I tried that too.

It's crashes with all maps.

The texture browser and model viewer make it worse, try not to use them.

ou can use the old model browser (Which is like loading a model into hlmv), But, there is no getting around the texture browser from what I remember.

Hammer shouldn't crash with no programs open and a empty map.

I have at least 8GB avaliable so it can't be a lack of ram.

I assume it to do with deleting the src maps folder.

I just had to cycle through each map to confirm to Hammer that they are deleted.

your trick might help others some other time though! thanks
