IE6/ Win XP SP2 - GetURL problem

I am currently having problem withusing getURL function only in certain scenarios.

With Firefox: Working fine

With IE6: When the query string is short it works fine but when Its bit longer it stops.

I tried athe solution at adobe.com about AllowScriptAccess method…It didnt help :frowning:

Any body had same problem or anybody have an answer, It would be a great help:)

thanks
