I also had this errormessage but did not figure out when it occured.
Maybe your example helps to track it down!

No Problem:
if the button is enabled, everything works fine.
But if you click at the DISABLED button an exception is raised.
The exact description of the exception is "Laufzeitfehler in Microsoft
JScript: 'this._dragCache.sourceWidget' ist Null, oder kein Objekt.
the (sorry - compressed) Source code is:
this._dragCache.sourceTopLevel=this._dragCache.sourceWidget.getTopLevelWidget();};proto._handleMouseMove=function(e){if(!this._dragCache){return;}
i hope this helps. if not, feel free to ask for more

Hello Sebastian.
please have a look at this code snipplet.
it is part of my wizard.
Please run the script and click at the disabled button. then you can
see, what is my problem!
No, please explain it a bit more. Just send out examples is the most
time not really helpful.
Sebastian
P.S. this error only occours, if the button is inside the
Layout-Manager. A simple button like in your demos wors fine.
P.P.S. you can delete the hints, it's only for better reading (i
hope, yu can understand german ;-)
