question on logiclib

[jsbach]

i have:
...
var Var1
var Var2
...
${If} $Var1 <> $Var2
; do action 1...
${Else}
; do action 2...
${EndIf}

When values are different i expect 'action 1' being executed but this never happens. for example:
Var1 = "1.3.1.0"
Var2 = "1.4.1.0"

i'm getting 'action 2' executed. Why ?

thanks.

ps. not yet tried with latest version of logiclib (just downloaded). Now using lib which comes with nsis 2.06.
