[mapguide-users] DigitizeLine instantly returns null linestring without user input

Fri Dec 30 17:43:29 EST 2011

In ASP.NET/C#, I have a Invoke URL page in the scriptFrame that calls the
DigitizeLine() function when the page is loaded. This is done via the
ScriptManager in code behind. The trouble is, about 50% of the time in
Firefox the digitize cursor appears and immediately resets returning a null
linestring. In Internet Explorer this behavior happens 100% of the time.
