Finally my last message is not correct because i changed my graphic card with a GetForce GTX760 and i cannot open my project file. 9 times out of 10, my computer refuses to open my project file and windows 10 closes Iclone! Probably, the graphic card is not involved.
I did the test with two computers now and it is the same thing. The first one is i7/8Go/GTX750Ti/windows 10. The second one is i5/8Go/GTX760/windows 10
The conclusion is when the file is too large (about to 240 Mo) a problem occurs between Iclone 6.4 and windows 10 and file project is not loaded.
I attach the jpg file which contains data from the "newpaper of errors" of windows 10. I'm not sure of the translation. Sorry for my english.
Since several weeks, I am very Bored with this bug. Am I the only in this case ?
Thank you for your help
