I have run into a strange problem. On a few Vista Machines, when a liveimagebutton is clicked, the following error message is generated: 'Cannot use a leading .. to exit above the top directory.'
It does not happen on my Vista computer but I have seen it happen on other people's computer when I shared their screen. At first, I thought it was my code so I removed all code behind the button and it still happens. I know it will be very difficult to reproduce because it rarely happens. I am hoping someone will confirm my observation. Here is the stack after it happens:
Error Message: Cannot use a leading .. to exit above the top directory.
error Source: System.Web
targetSite: ReduceVirtualPath

Hi,
I have no first-hand knowledge of this error, but a quick search on Google does turn up several hits, with at least one thread that includes developers posting their solutions.
