I'm working on a GUI application, but I've noticed that when I click on the various checkboxes, I lose the ability to accept commands via the keyboard.

Is there any way to restore focus to the keyboard at the start of every frame?

Use these routines, and you'll have keyboard input *always*!

you need this as well:

.lib "user32.dll"
GetAsyncKeyState%(virtualkeycode%):"GetAsyncKeyState"

if you don't want to include the dll-file then try this trick I have found to work:

dummy_window = CreateWindow("",100,100,0,0,0,32): FreeGadget dummy_window

After that code in your program the keyboard will accept input again.
Please give me feed-back, if it works. Thanx.

I still can't get this to work properly. Surely there's a simple way to restore keyboard focus at the start of a frame...?

Did you actually test that before you posted?

Aha! The wonderful Mr Sibly actually pointed me in the right direction with this.

Bascially, the trick is to call ActivateGadget after a button or checkbox is manipulated - this will restore Keyboard focus to the gadget you activate (in my case, the main window).
