Hi all, yesterday I updated my 1.5 branch to r19653, compiled and installed. The only changes I could see during the update were to .po files. However I didn't restart LyX that day.
Now this morning I was unable to start LyX, in the sense that nothing happened when I ran the executable. Updating to r19676, compiling and installing, seems to have fixed it. If you recall, I had similar behaviour a few months back but couldn't investigate as I installed a newer OS and it didn't have the same problem. Have fun, Darren
