It hangs but seem that only with synedit have problem as I can see (synedit 
inside TPageControl) - just start IDE and click into SE source, now try to 
click another SE tab.Seem that something strange is happening when synedit is 
focused by mouse, since keyboard focusing (via tab) works ok.
eg .TTreeView works fine.
