We are using IBM Rational Developer for Power Systems Software Version 8.0.0 LPEX Editor for RPG programming.
When I use the mouse to highlight a block of text, and then later try to highlight a new block of text elsewhere, the editor assumes that I want to extend the original block. Quite annoying. Double-clicking in a random area sometimes clears it, but seems arbitrary and unpredictable in its result. It seems that the first highlight sets an anchor point which remains until a successful double-click clears it. I suspect there is something in the preferences I can set to make it work more like every other editor I've ever worked with, but I haven't found it yet.
I want each start of highlighting a block to be a fresh experience.
(A google search found someone else who had the same problem, but there was no solution listed http://itknowledgeexchange.techtarget.com/itanswers/wdsc-highlighting-just-keeps-going-and-going-and-going/
