5 years ago Hi Raoul, Please update the graphics driver. That should fix the problem. Cheers, Ajay

Recently I saw that drishti 2.6.5 has been released. When I try to load a volume dataset it gives me an error and closes. I've been using 2.6.4 so far, and never had this issue with that version.
Steps to reproduce:
- open drishti
- file / Load Volume / Load 1 Volume
- select a drishti volume file. (I verified that the same file loads without problems in 2.6.4, but the file was produced with the import tool that is distributed with 2.6.5)

If I can do anything else to help resolving this issuse I'd be happy to do so.
