QS doesn't perform commands

[philostein]

I think this is new to ß68.

QS stops performing commands. They can be typed and executed, and QS disappears, but nothing happens.

A restart fixes it.

It's happened to me at least 3 times, and it's happening now. Here's a current log sample:

[pjrobertson]

I think I've seen this once or twice, a restart always fixes the problem.

[pjrobertson]

OK for when the 64 bit change is over, this is caused by my change in 4139476

Options for fixing:

• Return to using a temp array
• wrap the calls in @synchronise(iconLoadedArray) messages

[skurfer]

I’ve seen this too, but couldn’t reproduce it reliably enough to make a good report.
