start:
call  configLoad
cmp   [configExists],1
jnz   .startNoConfig
; this works correctly if the config file does exist


proc WndProc blah
cmp   [configExists],1
jnz   .wmInitDialog_NoConfig
; this does not work at all, whether I compare to 0 or 1
endp


proc configLoad
  local wfd:WIN32_FIND_DATA

  lea   eax,[wfd]
  push  eax
  push  applicationPath
  call  [FindFirstFile]

  je    .existNo
  jmp   .existYes
.existNo:
  mov   [configExists],0
  jmp   .existEnd

  push  eax
  call  [FindClose]

  jmp   .existEnd
.existEnd:

; this works here as well
