Bug ID: 58304
           Summary: Question on programs that use files with $ in file
                    names?
           Product: Wine
           Version: 10.8
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

Use Pegasus Email, and it works fine under one except if on tries to use the
IERenderer extension. With the extension installed, if one tries to open an
html email the call to the IErenderer.dll causes Pegasus to hard crash..

The Pegasus creates some temp files from the email message, and uses
WPM$xxx.PM$ format for files. Was thinking perhaps in the passing of filename
with $ inside them might cause issue since Linux treats the $ as marking a
variable?

With IERender extion it creates these two file
     1110  05-16-2025 08:18   WPM$M1PL.PM$
    56167  05-16-2025 08:18   WPM$SXGZ.PM$

With extension uninstalled it creates these 3 files
     1536  05-16-2025 08:15   STO30e6.tmp
     1536  05-16-2025 08:15   STO30e7.tmp
    56167  05-16-2025 08:15   WPM$Z65Z.PM$

Note both of the 56167 byte files are identical??

The purpose of extension is to better handle displaying html messages.
Without it, some messages don't display as they should. One can then opt to
open messages in a browser, and they will display fine, but then replying
doesn't work.

Don't know if changing the $ to a different character (perhaps _) would avoid
issue.
