If you try to run Uniform Server from a path that contains paths (i.e. c:\program files, c:\documents and settings\), an error pops up stating "spaces aren't allowed". It raised quite a bit of forum topics (e.g. this one). I figured it's time to add it to the tracker.
When you register to this forum system, there's a challenge question. It asks you to count down from X to Y without stating commas are needed. Due to the usage of ReCaptcha, it takes quite some tries to figure it out alone... Please mention that commas are needed.
