64-bit or 32-bit Windows? Which browser? What does the commandline look like?

Since loading Pegasus 4.63, hyperlinks in emails invoke the "Programs" directory in Windows Explorer rather than opening a tab in the default browser. Version 4.61 does not show this problem. (One can alternatively work around the problem by using a non-default browser, selectable by right-clicking the link.) Switching the contents of the "Programs" directory to that of version 4.61 resolves the problem - it does not appear to be a function of the configuration. If this is not a bug introduced with 4.63, how can I track and resolve it? (OS is Windows 7, fully updated.)

Close winpm-32 and then navigate to where winpm-32.exe is located and run setpmdefault.exe and then you can restart Pegasus Mail again to test.

Also check Tools, Options and Hyperlinks and check find automatically and clear any entry for web browser command line. Running the System Mailer button does the same as running the setpmdefault program.

To check default programs and associations and protocols you would do so from control panel or Start menu of Windows and

Control Panel\Programs\Default Programs\Set Associations
