Hi

I'm faced with a weird behavior.
Net Office task panes are not visible anymore in Excel 2013 when an XLA is enabled.
To reproduce the problem, I used any of the samples provided creating a task pane, and I active an XLA.
Each of "Solver addin", "Euro currency tools" and "analysis toolpak" XLA provided with Excel 2013 creates the problem.

A workaround is to uncheck "Show the Start screen when this application starts" in Excel options "General" (at the bottom)

Any idea what is going on ?

Thanks

After further investigations, moving the creation of a task pane (ICTPFactory.CreateCTP) outside of the ICustomTaskPaneConsumer.CTPFactoryAvailable method solve the problem.If that helps ...

Yes, exactly, the pane is not visible, but there is no exception anywhere, all code run as it should.

Current implementation of custom task panes in NetOffice supports only single instance of a task pane.
