this isnt necessarily a problem everything does function fine just it really annoys me. using the "USECOM" example ive made my application not appear in the taskbar, however for like a second it appears then disappears, this is what annoys me. i know its because the code which makes it disappear from task bar initializes a split second after the program is actually put in the the taskbar. there must be another method of doing this so it doesnt appear for a split second, ive seen a fair few other applications do it unfortunatly i cant look at their source Crying or Very sad . heres my code:

format PE GUI 4.0
entry start

include '..\..\include\win32a.inc'

struc GUID def
   match d1-d2-d3-d4-d5, def

      .Data4 db 0x\#d4 shr 8,0x\#d4 and 0FFh
      .Data5 db 0x\#d5 shr 40,0x\#d5 shr 32 and 0FFh,0x\#d5 shr 24 and 0FFh,0x\#d5 shr 16 and 0FFh,0x\#d5 shr 8 and 0FFh,0x\#d5 and 0FFh
