Had the same problem as above. I downloaded the DOSBox software and it works great; at least the latest version! Fixed all the the issues with the sploches over numbers and the game seems to run fine with no other issues or errors. I use Windows XP so I do not know if DOSBox will work or fix this issue under VISTA, although I see no reason why it should not work.
I had this problem on my notebook, and also wonder (in addition to font issues) if it may also have something to do with having a 9:16 ratio display? I have no issues running WIR on my desktop; same version of Windows, and same computer manufacturer, but with a 3:4 ratio display.
Some advise. DOSBox is an enhanced MS-DOS emulator program (DOS 5.0 emulation) that runs an MS-DOS virtual machine under Windows through which it loads and runs WIR. While you can configure WIR to load from the Windows desktop using this program, a limited knowledge of MS-DOS, the DOS prompt commands, and DOS batch files will be of help for installation and configuration. Those of you who are only familiar with Windows may have a bit of a learning curve although the tutrial does offer a reasonably good step-by-step for configuring the program. Note that DOSBox is also free, although a donation is requested if you like the software.
The software can be downloaded from www.dosbox.com.
I do not know if anyone is having similar issues with Pacific War (PACWAR), but DOSBox also seems to run this game with no issues.
I hope this info helps.
