[Geomoose-users] Curved labels and libgd or gd.

Its  worked alright, the op system didn't show any errors and angle follow does not curve my labels like it should. But I suspect there's something wrong with my windows installation such that certain dlls can't be accessed on the expected path? I may be wrong but I wish it  were working, seriously.  Franz Okyere.
