Note: There is a bug in Adobe AIR 24 (currently the latest version) that can cause this problem. We expect Adobe to fix it in AIR 25, but meanwhile, follow this procedure to make sure you have AIR 23 installed:
1. From Windows Control Panel, uninstall G-Wizard Editor and Adobe AIR.
2. Download AIR 23 install from this page: https://helpx.adobe.com/air/kb/archived-air-sdk-version.html
You want the "AIR 23 runtime download" for your platform.
3. Run the AIR 23 install.
4. Run GWE Install (http://www.cnccookbook.com/GWizard/GWEInstall.html)
5. If AIR asks to update, you have to tell it you'll do it later or it will just drag in AIR 24.
If you're running AIR 23 and still have problems, then this is a driver problem. Sometimes, Windows (haven't caught Macs doing this) updates its video drivers to more generic versions that don't have all the latest fixes. You'll need to find the latest driver for your particular graphics card and install it to fix this problem. There are 3 good links for the latest drivers on this Adobe page:

If the suggestions on that page don't work, try setting it to software rendering. To do that, add a file named "GWESoftwareRender.txt" into your "My Documents" folder (or the Mac equivalent). It doesn't matter what's in the file so long as it exists. Restart GW Editor and see if it'll paint correctly in software rendering mode.
