This program was a must have!! My phone recently had to be replaced and I lost this program, among other things, and want it back. Where can I find it again?
Note from the webmaster: The download link has been fixed.

Used magic button in the past, but didnt like the way it adjusts the GUI on WM5. Found inclose late last year, vasty better program, like the exclude function means I can keep my outlook mail open allday with no start up delay. Bigger app, but worth it. I believe a new version is due soon!

It worked well, but there's one HUGE flaw... you can't press "OK". You know how sometimes you enter information, and on the top right, instead of an X, it'll say "OK"? Well, this program basically minimizes (or closes) whatever window that is (depending on the setting), as opposed to actually pressing the button "OK". This'll mess some of your settings up I'm sure.

I found this program while browsing freewareppc with my MDA. I downloaded the .cab file and installed it. It is a must have! Great work!

Seemed to work very well,but after installing it iPAQ backup stopped working. I'm back to MagicButton.

Both installers for WM2003SE don't work properly "connected device not supported". Does not support the out-of-the-box std VGA-mode when using WM2003SE.

Works fine for me -- supplies functions Windows Mobile 5 does not offer (such as ad-hoc change of orientation, really exiting an application). I recommend it.
