I have installed the 64-bit version of Inscape for use on Windows 7, but the colour scheme is dark grey, so that the icons do not show up clearly.  The 32-bit version has a cyan colour scheme.  I cannot see any option in preferences to be able to change the background colour from grey to cyan.  Is this possible, or must I install the 32-bit version?  I am very impressed with the program, which will be used to prepare drawings for cutting out parts for making model trains and buildings.
