AXavierB, no, the stability issues haven't been touched upon in this build. There may have been a plugin stability problem or two fixed. Most of the instability problems are with the construct classic ide itself. There aren't alot of problems with the exe's construct creates. As long as you save often, and to incrementing filenames at least sometimes (ie myproject.cap, myproject2.cap, myproject3.cap, etc) you should be fine. Its very fast and powerful. Just a few quirks to deal with here and there
Edit: ash beat me to it. oh well. Already typed it
