Parameter is not valid - Infragistics.Win.UltraWinGrid.ExcelExport.UltraGridExcelExporter..ctor()

"Parameter is not valid.

at System.Drawing.Graphics.GetHdc() at Infragistics.Win.UltraWinGrid.ExcelExport.UltraGridExcelExporter..ctor() at Infragistics.Win.UltraWinGrid.ExcelExport.UltraGridExcelExporter..ctor(IContainer container) at MyGrid..ctor()"

For some reason, after a period of time, whenever one of my win forms loads, and there's a grid to be initialised, I get the above error. The error persists until the application is restarted. Has anybody else seen this? I am using 8.3.20083.2021. I'm sure I've seen somewhere that it may be down to the number of window handles it uses up, as there is a leak of sorts. I realise that I could upgrade to the latest version, but management will not allow this unless there is a very good reason as it envolves a mass roll out to thousands of user machines. Perhaps there is a hot fix.

If somebody could let me know in which version it was found and perhaps in which version is has been fixed?

Thanks for any help, Andrew

    Hi Andrew,

    I've never seen an error like this before that I recall.

    I suppose a memory leak could explain this. That should be easy enough to check. Bring up your task manager in Windows and there's a Performance tab that shows you the current number of handles.
