fix Stack overflow line 20 error easily

Some users have posted on numerous software forums about a Stack overflow line 20 error that arises in their web browsers (especially Internet Explorer). That error can occur when you try to log in to sites. One user stated:

Message from webpage… Stack overflow at line __. You can click OK on it & it will keep popping up with a different line number.

The stack mentioned in the error message is a section of memory (RAM) for software to store variables and program parameters. Stack errors (otherwise overflows) arise when programs exceed their call stack memory allocations.

Those stack overflows often arise from Java, C++, and Perl runtime environments for browser applets.
