Here is my setup
*The AdvanceHMI v3.19
*Using Visual Studio 2008
*Micrologix1100 connected to COM3
*16 Input 10/30 VDC Expansion mod(1769-IQ16)
*16 Output Relay Expansion mod(1769-OW16)
*SquareIlluminatedButton with the PLCaddressvalue set to O:4/2 <-flickers
*Any controls referencing address' on main PLC <-no flicker

The address is on an output expansion module. I also have input expansion module were all controls flicker if given an address on the expansion module. I have other controls on the screen that don't flicker and i've found that its only when they reference an I/O on an expansion mod.

Per the other posts, i have checked the empty values, made sure the ".OnPaintBackground" coding was commented out, and my form has DoubleBuffered enabled.

Any suggestions?
