another window fault (please forgive in advance)

[ace rimmer]

i have an early boxster and both front window regulators were broken, both were replaced and now when the roof is down everything is cool , however when the roof is up the windows stop about 3 inches from the top, if you turn the key in the lock till the window go's up to top then once you start the engine it go's back down, help please, at least untill the good weather is here
