UltraDesktopAlert raises "Parameter not valid" and crashes app.

215

I use the alert to notify when an item is deleted.

I open the form and delete an item and the alert shows. No problem.

I close the form and open it repeatedly - 10 times.

I delete an item, the application crashes withan argument exception "Parameter is not valid."

It's crashing on the line

Show(windowInfo);

All that gets set in windowInfo is as follows:

image, screen position and caption and location.

Is there any reason why "Parameter not valid" is raised - What would make the UltraDesktopAlertShowWindowInfo variable stop being valid.

I ran throught this through the debugger and it is not null - variables there at run 1 are there at run 2.

Would appreciate any help on fixing this.

Thanks
