Quote from TIKITRADER:
Anyone interested that is using QT and having trouble with lines disappearing. Wrote to them recently and they replied with a possible fix. Here is what they had to say regarding this problem . . . Please get the update at http://download.quotetracker.com/download/stocks.zip
and extract the contents of that file into the QuoteTracker folder, overwriting the existing STOCKS.EXE file while QT is not running and let us know if you still have the problem.

Much appreciated... Looks like all of our efforts in emailing them about this may have paid off. I had stopped drawing them altogether because I'd get so pissed when they disappeared on me... (same feeling you get when a power surge fries your computer and you lose a 20 page paper that is due tomorrow).
