But which DLL you get depends on the PATH environment variable, among
other things.  How do you know it's set the same when your DLL is called
from the browser as it is in depwalker's environment?

You might try renaming the directories with those other Qt versions to
see if the error changes.  Or use a tool like FileMon to see which of
