Hey, I like this UDF But i have a Problem with this UDF. If you for example have an error in your Script: global $error[1] $error[5] = 4 AutoitIT and Scite shows this error as soon as it hits this script line. if you put the above error right after: _GUICtrlTreeViewTab_CreateTab and run the Script. Autoit Hangs/Crashes with no error information. I have a larga Script and its hard to find simple mistakes like this. I have to uncomment: $ah_TVT_WinProc[$ah_TVT_WinProc[0][0]][1] = _WinAPI_SetWindowLong($hParent, $GWL_WNDPROC, DllCallbackGetPtr($h_TVT_WinCallback_Proc)) in the "_GUICtrlTreeViewTab_CreateTab" function. Then Autoit Shows me the error like it should. But switching "tabs" is not possible then. Anyone has an idea what is causing autoit not to show errors after "_GUICtrlTreeViewTab_CreateTab" ?
