### Known Issues

- Old IE version can cause crashes when handling archive files.

  Workaround: If WinMerge crashes when handling archives, consider updating IE to version 6.0 or later.

- Supercopier application causes WinMerge to hang.

  Supercopier application causes WinMerge to not exit properly and leaves WinMerge process hang. See the bug reports:

  - #1976241 the winmerge.exe process doesn't stop itself
  - #1602313 WinMerge stays in tasklist after closing

  Workaround: Disable the Supercopier when using WinMerge.

- Filters only applied when using full compare.

  Line filtering is only applied in folder compare when using Full Contents-compare method.

  If you are using any other compare method, line filters are not applied. Files marked different in folder compare can get status changed to identical when opening them to file compare.

- Unset WinMerge integration from ClearCase

  To remove WinMerge integration, you'll need to edit one file by hand:

  1. Find ClearCase installation folder
     Usually it is something like `C:\Program Files\Rational\ClearCase`
  2. Go to subfolder `lib\mgrs\`
  3. Open file `map` in there to editor program
  4. Comment-out the line starting with "`text_file_delta xcompare`", containing "`WinMergeU.exe`"
  5. Uncomment the line starting with "`text_file_delta xcompare`", containing "`cleardiffmrg.exe`"
