Microsoft has updated its handheld synchronisation software to address a glitch that prevented users mirroring data with a desktop.
The problem affected users of mobile devices running Microsoft’s Windows Mobile 5.0 operating system.
The company has released Microsoft ActiveSync 4.1 to solve the problem, which saw users having trouble synchronising data via a USB connection when a firewall or parental controls were in use on the PC.
Users synchronising data via a server or over a wireless network were not affected by the flaw. The fix is now available from the Microsoft website.
Windows 5.0 is now starting to make inroads into the mobile device market, which Microsoft first entered in earnest five years ago.
The operating system competes with the likes of the Palm, Symbian and BlackBerry operating systems in the mobile space.
