atx4us #1 Posted May 8, 2009 Original Posting: http://www.atariage.com/forums/index.php?s...=141758&hl= I finally figured out how to use the OSS Action! cartridge with Atari800WinPLus 4.0 without the keyboard locking up - It's easy! Go to the Keyboard Options menu and be sure to Uncheck the "Use Windows typematic rate" control. That's all to it. Quote Share this post Link to post Share on other sites
