Hello Gnozal,
I got an error with the 253 version of PureFORM which is hard to reproduce.
First I started a new project with a few gadgets (see screenshot). To modify the tab order I clicked then into the gadget list within the Integrator window. By doing this I clicked accidentally the right and left mousebutton various times.
After this I got immediately the errormessage shown in the screenshot (dont' wonder about the textgadgets, because I erased the texts in the sceenshot for security reasons. The programm will be part of a User-Register-Check for commercial software).
I tried to reproduce this issue, but I could reproduce it only one more time by clicking crazily RMB and LMB within the gadget list. So it's not a urgent issue, but at least you are informed about this.
Bye Markus
PS: I'm able to reproduce the problem with the current 255 version too.
PS2: Gnozal, another idea regarding the enhancement of modifying the tab order: In some other GUI Designers I use at work you can assign the tab order by activating a special "tab order recording mode" and then clicking on each window element in the wanted order. The GUI Designer records the order and set the taborder of the elements to the order which they was clicked (I hope I explained it understandable

).
