Why are you creating gadgets in your mainloop anyway?

If you want to hide a gadget depending on a variable, then use HideGadget gadget and ShowGadget gadget.

The correct order is:

1: initialisation & create
2: mainloop
3: cleanup & exit

I dunno I thought like

Case 1
; Show this here

Case 2
; if it case 2 it shows whats here and case 1 doesnt show

else with hide, doesn't it just stays in the memory till you show it again?

Don't worry about the memory.. we aren't talking megabytes here..

Anyway, I checked that source, the tab shows up when you drag the window around. The tab works when you move the creating process above the loop.

There must surely be a reason why things don't work. I don't think I would ever find out, and I don't need to. This is simply not the way it should be done.. :)

Just stick to this:
1: initialisation & create
2: mainloop
3: cleanup & exit
..and everyone's happy..

put in a timer *before* ya main loop

createtimer(5)
repeat
...stuff
until keyydown(1)
 

else nothing gets updated until an event is caused, such as dragging the window.
