I have a really complex application with nested TabControls and sheets containing a lot of skinned components(ScreenDump)
The problem occurs with changing of the active tabsheet OR even hiding the whole panel.
If I change the tab sheet on the lowest level (SmartEdit/Suchen)- there is no problem with timing <1 sec.
Changing of the middle level (Data,Info,Feldliste,SmartEdit) takes more than one but <2 sec.
Change it on the higher level (adding a new sheet) – it takes more than 15 seconds! delete needs even more until it's really removed.
If I switch off skinning – it changes in fraction of a section…
All the components used are inherited from sAlpha controls.
