well, my v9 build 1104 crashes often when doing stuff in the part-to-sheet layer. on my sheet i marked all my dimensions, i did a print to my color printer, and after that the sheet layer was not visible on screen but was still selected in the layers panel. at this point it looked like it stopped working completely, i could not change layers or anything, then i got a Crash message popup from the program, said it created a crash dump file, which it did, so i will send to Punch.

so, this ver of 9 seems to be a tad unstable, at least on my PC where v8 was working just fine.
