Why does my external manifest work only sometimes?

[uligerhardt 19]

In the attached project, the internal manifest is disabled in the project options. Instead an external manifest is supplied (ExternalManifestTest.exe.manifest).

 

Now if I compile the project and run it from explorer, the main form shows up themed as expected.

If I rename the manifest and run the app again, it shows up unthemed - again as expected.

Now if I restore the manifest's original name and try again, the app still appears unthemed - not expected.

To make it recognize the manifest again, I have to change the date of the exe file (by recompiling or using something like "touch").

(Windows 11, Delphi XE6)

 

Why is this and how can I change it?

Thanks, Anders!

Very interesting. After reading a bit I decided it's easier to stick with my "touch" solution.
