In an clean install of the mIRC i am not able to see this bug, when i saw this bug i use /remote off and trying to move the switchbar and waiting to fix, but i have not any dlls,coms in use only some un useful codes that have not effect the switchbar! so i cannot check why this is happening but i thought good to report and track an video to give you and maybe you will know the why, i think the problem is while i open an query window or an custom @window the new window that is opening does not sort in the switchbar correctly in some situations.
