Forums mIRC Help is this a bug or something else?

Well... I installed mIRC version 6.21 about a month ago, and havent had any problems until i was scripting a program today. The problem I ran into is having mIRC not finding a the filename "global.ini" existing in a directory on my computer. For example, i ran this code earlier today:

echo 4 -a $exists($+(",$mircdir,bot/global.ini"))

output:

$false

eventhough the file exists in that perticular directory and is named global.ini mirc found it none existing. mIRC wont even write to it because it states it none existing. However, if i was to rename "global.ini" to "gobal.ini" and impliment the code as:

echo 4 -a $exists($+(",$mircdir,bot/gobal.ini"))

output:

$true

I do not know if this is a bug or if it is something that mIRC no longer supports.
