Only if active is meant to cause the watch window to quit polling for values if
some other BricxCC window is the active window. When graphing this means that
after you bring up the graph window you need to click back on the Watch window
to make it active again or else no data will get added to the graph. I just
noticed that I accidentally introduced an empty series into the graph form
called Series1. It will be removed before the next official release.

In the RCX the 3 counters overlap the first 3 variable slots. And only global
variables can be accessed in "immediate" mode (i.e., the mode BricxCC uses to
poll for the values it reads in the Watch window). Variables declared inside a
task are usually local variables but that depends on whether there are any local
variables available for NQC to use. If there aren't any then NQC falls back on
using global variables.
int a; // global variable
task main()
{
a++;
int x[16]; // there are only 16 local variables
int y = 10; // so the rest are global variables
int y1 = 10;
int y2 = 10;
int y3 = 10;
}
*** Var 0 = a
*** Var 32 = x
*** Var 1 = y
*** Var 2 = y1
*** Var 3 = y2
*** Var 4 = y3
*** Task 0 = main, size: 25 bytes

This is a bug in the non-MDI (tabbed) window mode. If you use the old MDI mode
it works correctly. I will figure out a way to make it work correctly in tabbed
mode as well and get the fix into the next official release.
