Add DPI awareness to manifest (fix #7)

[MattSturgeon]

I tested @roblarky's suggestion and found it fixes the DPI issues completely for me. I've marked him as the author since all changes are his, but it would be good to get this into an AltDrag release in the near future 😃

Testing

Here's a .zip of my build directory in case anyone wants to try out these changes without having to compile them.

After extracting, you can either run AltDrag.exe directly from the bin directory. You can also run the installer (AltDrag-1.1.exe), but be sure to manually undo the workaround as it will conflict/override these changes.

Alternatively you can of course use the normal method to clone and build this branch if you don't want to trust my binaries.

Glad to hear!

Hello and thanks for this awesome program,
Altdrag is the first thing I install on windows when forced to use this OS. (at work for instance)
Much appreciated is the portable app: so no admin right is needed on locked machines.

This fix calls for a release I deem.
A release is needed urgently: last release dates three and a half years back.
I can fill a separate bug if needed.

Reporting in: it totally fixed the problem, thanks!!!

In particular I should mention: it fixed the problem when dragging across two monitors with different DPI, there was a problematic feedback loop, which turns the target window infinitely bigger and bigger.

Now it looks like the coordinates are consistent across the boundaries!

Is there anyone who can fork this project and apply criticals PR like this one ?
...And provide .exe ?

Thanks

I just tried alternative mentioned here #124, seems more up-to-date

@Arnaudv6 Thanks, Absolutely Fabulous, v1.4 working great !!

This excellent fork should have a better visibility, why not adding a redirect to ?

This solved all the issues for dual screen and different DPI settings in each screen on windows 10!
Super smooth!

Thanks
