Bingo.

We've considered that. It causes other issues, but may be a last resort.

OHOHOHOH.... I think you have something there my friend... I think that may
just do it.... Won't work on lunix systems, which are a minority in our
project, but may be the best method I've seen to date!
Thanks!!!

OTFL... Heheheh, yeah, kinda kookie.
We are a very small company. I am the only real employee, and I personally
have supplied all the funding (I often think of spike lee, who maxed out his
credit cards and went into hoc for his first movie...). My wife and I are in
debt up to our eyeballs :( but both believe in this project.
We've been lucky with our graphic artist. He'd done the job for 1/10 it's
actual value. However we've had a very hard time with the programmers. We
had a few who pretended to work, some who padded their resumes and had no
experience, and some who got halfway through and found something that pays
more....
Of the two programmers we have now, one has been fired, and the other, while
excellent, works full time at lucent. When he does give of his time, its on
much more serious issues.
I used to program in Pascal, and have spent the last 6 months learning
Java... I know relatively little, but am able to fix a few small bugs a day,
while our remaining programmer works on systemic issues. I post here because
he doesn't know the answer, and I need him working on the big stuff...
This is a very seat of your pants operation, though on the website we've
worked hard to hide that fact... It's got no budget, and has been very
difficult... But we're getting there... :)
