Softimage crashes when modeling

[Talik]

Hello. I have an issue. Softimage is known very stabile but it crashes when modeling. I think that this comes because the addons I have. Softimage version 2015/ I'm using a tablet.
Does switch to early version solve this issue? Or how to fix?

Just remove all your add-ons and test SI alone
If it works then go to next step below if it doesn't work maybe a software problem --> Reinstall.

Install each add-on one by one and test each time with SI. You will find the add-on problem.

Since crashes come randomly it's not easy to test everithing.
Yes I have tested and reinstalled XSI. I tested it even on another computers.
I think the number of crashes is been reduced since I uninstalled some addons that affect viewport like "QuickInset". But sometimes crashes still appear.
Do you know which addons are certainly unstabile and make crashes? I could start testing from them.

My plugins folder is even simplier.
Did you notice that some of plugins are not campatible when have both of them installed? Especially those ones that interact in viewport. Like slice knife, smooth loop and many others. The only that I left is six point aligh.

By the way does bridge to 3DCoat work? It's outdated

[bvmadjen]

the bridge to 3dcoat does work, as I have 3dcoat 4.9
