I've been revising and compiling my project with FF3 for days without a problem. Tonight I changed the version number in the project properties and the value of one assigned variable in the program. Now when I press F5 to compile the progress bar comes up and seems to compile but the program never starts. If I run the executable, the older version comes up and not what should have been the newly compiled version. This is really weird.
I brought up one of the FF3 example programs and F5 runs as expected.
I'm scratching my head on this one.
I solved this one. It turns out that the program was still running in memory. I used the Task Manager to kill it and now the compile works fine.
FF3 tries its best to determine if another instance of the program is running in memory prior to initiating a compile (a much better job than FF2 did). However, it is not an exact science so sometimes it may not detect the running EXE.
