'Cannot make a visible window modal' error

[Topher]

I'm trying to set up a couple more jobs while one's running, but I keep getting this error. I'm running AGK 2.20 on a winxp computer. I don't remember getting this with other versions.
Is this because a job is already running?

can you describe step by step what are you doing to reproduce this problem, please?

I was converting a dvd & it was in the middle of re-running the first pass when I decided to add a couple more jobs to the queue.
The error popped up when I tried to open the directory I had ripped the second dvd to.
Once the conversion had finished, I was able to create one job & then create a second job as long as I didn't start the first job.

are you able to constantly reproduce this? (coz I can't)

I tried it again last night & everything worked fine. Maybe it was rebooting my computer.
Sorry for the false alarm.
