I have had similar problems. My scenario is that I start a database/table copy in one instance of sqlYog and use another instance to monitor progress (select count(*)...).
I minimize both instances, occasionally opening the monitor instance to check on things.
Then I hear the completion noise from the copy, but I can't un-minimize it. I see the original copy dialog, but it is unresponsive. The copy instance doesn't show up in the alt-tab list and the right-button on the task icon does not provide a menu. Killing with the task manager seems to put things right again.

Recently I've got some similar problems related to the SQLyog (ver 5.0 final) window refresh/repainting.
We have many servers in our office intranet and I mostly have two connections to different hosts using same SQLyog instance, sometimes three. Last week I've opened 4 or even 5, and SQLyog has suddenly stopped window refreshing: just window border was visible and some icons. F5 was executing current query but only result grid was repainted; remaining screen remained unrefreshed: some parts of other windows were visible. Minimize/restore window did not help. I've tried to close single connections (Ctrl-F4) but with no success. After program restart all was fine again.
Few days later I've got exactly same problem again, and again after opening 4th or 5th connection.
I'm using Windows XP Professional with SP2.
