Java is a great programming language and platform to work in but in it's best moods it is, at best, a pain.

Today I fixed a huge issue that I thought was just with Java, but discovered it was so much more than just Java's fault. An application I use on my Mac called Flexiglass was causing problems. 

When I open a menu item within a Java application (such as the basic GUI builder in my ZPE editor) I get the following error: 'component must be showing on the screen to determine its location'.

This comes from Flexiglass, since Flexiglass changes a few system properties and therefore interferes with Java's menu system in some way or another. Anyway, the fix is to turn off the two checkboxes as pictured below:

The simple fix is to switch off two checkboxes
