AdvToolPanelTab problem with locking/unlocking panels.

If I set property AdvToolPanelTab:Position = ppRight, event OnLock decreases 2px property AdvToolPanel: Width, event OnUnlock decreases 2px property AdvToolPanel: OpenWidth. If user too many times Locks and Unlocks Panel then width Panel decreases.

I use VCL UI Pack 10.7.9.1

Thanks for reporting.
We applied a fix that will be included in the next update.
