Hi all,

;${ReadINIStrNS} $R0 "D:\Build\Builds\Code\test.ini" "data"
Section "OgO Open File Association" SEC02
Push $0
Call ReadINIStrNS
;Pop $0
;${ReadINIStrNS} $0 "D:\Build\Builds\Code\test.ini" "data"
SectionEnd


Function ReadINIStrNS
Exch $R0 ; key
Exch
Exch $R1 ; ini file
Push $R2 ; ini file handle
Push $R3 ; key len
Push $R4
Push $R5

FileOpen $R2 $R1 r
IfErrors End

StrLen $R3 $R0
IntOp $R3 $R3 + 1 ; inc. "="

LoopRead:

You need to pop the function's result off the stack, otherwise you're corrupting your stack.
