Plugin errors in webBrowser control after installing IE7.

Hi,

I have written a couple of applications that utilise a webBrowser control
axWebBrowser control in VS.NET 2003).

These webBrowser controls used to display files with extensions such as TIF,
DWG and DWF within the appropriate plug-in, so long as such a plug-in was
installed.

Now that I have installed Internet Explorer 7, however, I am getting errors
from all file-viewer plug-ins in my webBrowser control. The only exception to
this is PDF files which display fine using the Adobe plug-in.

I have tried re-installing the non-working plugins since installing IE7, but
with no success.

Interestingly, if I try to open a file, say for example a TIFF image, within
IE7 it displays correctly using the appropriate plug-in. However, the same
file will not display within a webBrowser or axWebBrowser control in a .NET
application.

How can I fix this problem?
