[IDV #WWP-385269]: IDV fails to start in Linux

Greetings!

In the simpleIDV script, look for (around line 4)

command="java -Xmx512m -Didv.enableStereo=false -jar ${dirname}/idv.jar -plugin 
${dirname}/simpleidv.jar $*"

and change

-Xmx512m

to

-Xmx256m

and try running simpleIDV.

Cheers!

Sean
