So now I have the newest Mp3tag and all updates of Windows 7 x64; and also made some adjustments to Winamp, checking quite thoroughly its options
But no matter if I have Winamp docked or not, opened or not running, the Filter box after closing and reopening of mMp3tag gets always either moved or resized [up]. I can counter this only by turning off the Filter before closing of Mp3tag, because then if I reopen Mp3tag and turn the Filter back on, it will show up just like the last time it was shown. And if I forget to turn Filter before closing, then I will have to once more adjust it
But if the Filter box is floating, then it works perfectly- its position and size gets always remembered; no matter where I place it and no matter if Winamp is opened / docked and what manipulation of other windows are perform
So my only user [to some extent] friendly option is to keep Filter in this floating form. Or to wait for option of "locking toolbars"; because maybe then that whole involuntary movement bug will be somehow blocked. And so I made a request: /t/18385/1
