This may have been discussed before (there's a blogpost on Darktable's home page describing the various issues regarding running the software on a 32-bit system), but I have a specific issue that I haven't been able to find any information about, so I'm trying my luck here.
The developers make clear that there are lots of problems associated with running the program on a 32-bit system. I too am experiencing some of this (for instance I am not able to see thumbnails of photos).
But the most annoying issue for me by far seems to have nothing to do with my system, but rather a feature (possibly a bug?) of the program. Every time I open a new image or switch between lightroom/darkroom/other I get the same warning message:
So in a typical 30 minute session of editing photos, I'll have to confirm my desire to suffer at least 15-20 times. Has anyone else experienced this when running the program on a 32-bit computer?
