Pasting Excel Chart into PowerPoint

[Jan]

When pasting a Microsoft Excel object into a PowerPoint presentation as an
embedded object (i.e. a chart as a chart not as an image), the in-place
editing fails if an instance of Excel (with a Vb.Net Add-In which handles
Excel.Application events installed) is open. It fails with a generic add-in
problem. The failure does not occur when Excel is closed or after the
instance from which the object was posted is closed. Vb.Net Add-Ins which
does not handle Excel.Application events seems to be working fine! Please
help!!

Error: "Microsoft cannot start the application required to open this object"

My Connect Class:
Using Addhandler instead of the WithEvents keyword resulted in the same
error...
