Using shell's IExtractImage pops annoying 'RefrehThumbnail' messagebox...

[ohadp]

I use the shell's supplied IExtractImage interface to extract thumbnail-images of files... When the shell tries to get the thumbnail image for a .url file, it sometimes fails, which is cool, but it also decides to popup an annoying message box saying 'The Page !@#!@# could not be loaded and rendered within the timeout period' or something slightly different on other OSs. Explorer obviously doesn't show these messageboxes, but how ? There doesn't seem to be a way to influence this through the interface, has anybody hit this problem ? thanks
