I work for a large corporate and my company is using Balsamiq 2.1.9 on virtual desktops. I have just had my virtual desktop build upgraded from XP to Windows 7, 32 to 64 bit. I have more virtual RAM, HD and processor bandwidth but Balsamiq now runs very slowly - it has been running well for some time on my old XP virtual desktop. On the new Windows 7 virtual desktop, opening an existing mockup takes about the same time but working within it (like selecting a simple object like a combo box) takes ages, up to 15 seconds before it is actually selected. I am going to lose my XP build at the end of the week and I need this to work at normal speeds on my Windows 7 build soon. Any help greatly appreciated.
