I updated to 4.3.0-46 this morning and noticed a problem that I have not seen in a long time. The z-order of the x windows in multiwindow mode seem to get confused. I think this is only happening if I go to another display in the MSVDM (MS Virtual Display Manager) and then come back, but I am not sure. The behavior is something like this:
Normally, if I have 3 or 4 x windows open and pick one from the menu bar or click on it, it comes to the top without a problem. When the problem starts to happen, what I see are overlapped windows and I cannot necessarily bring the window I want back to the top. This was not happening in 4.3.0-44. Sometimes, I can figure out the correct order to minimize windows and bring them back up and all is well. Sometimes, I just have to shut down all the windows and restart XWin. I checked XWin.log and nothing was listed after the startup sequence. - Andy
