CodeWeavers is offering its CrossOver Pro product for free on Tuesday, October 28 because the gas price in St. Paul dropped to US$2.79 a gallon. CrossOver is an application that lets users run Windows application on Mac OS X or Linux without installing Microsoft's operating system.

CodeWeavers has a special Web page for the free software offer, but interest is high, so expect to try more than once to get a serial number.

Current CrossOver Standard users can also upgrade to the Pro version for free and will get an addition 12 months of support. CrossOver Pro is regularly priced at US$69.95.
