Hi guys,My 1.3 #13299 image is blocked again, but just UI not responding to any input events, while Aida web app server is running smoothly in backrgound. > From Transcript I can see that last action was a new image backup procedure, which is done simply by : OSProcess waitForCommand: 'cp some.image some-bck.image'. This procedure is called from a background process and report to Transcript its start and end. Is there something wrong with that? Or is some interference with OSProcess semaphores? (I saw such suspicious thing once before). In any case, is there a way to unblock image now? Ctrl or Alt . doesn't help. Best regards Janko
For what it's worth, the UI blocking also happens occasionally (not very often, but occasionally) with Squeak 3.8/Seaside 2.8. But it's easy to unblock. Just run the "screenshot" app (within Seaside), then at the top there is a "Suspend UI Process" link. Click it to suspend, then click it again to unsuspend. That almost always unblocks the UI, although occasionally I have to suspend and unsuspend a second time, not just once.
But, because of the "screenshot" app is able to unblock it, the UI blocking problem has never been more than a minor inconvenience.
