Anyway, the problem is that under a certain condition, GUI buttons are affected by a gui.settext command. The text width inside the button will overflow the button boundaries causing the 'activated' colour to overwrite other objects. This usually only happens after a few presses, but not of the same button and only occurs when (as far as I can discern) the text in the GUI text box is the result of an IF THEN statement ?!?!?!
There may be other conditions, but setting a simple variable does not show the effect.
This is with Annex32 CAN 1.60.3 LFS and tested on two different boards, one a ESP-2432S028 with ST7889 driver and one a ESP32 with standard ILI9341.
Also, it appears that the GUI handler is not fully reset on a program re-run as the previous run's screen will reappear after a TFT.INIT and a TFT.FILL, when a REFRESH or AUTOREFRESH is issued.

' Setting Result$ explicity does not cause the error
