I'm having trouble controlling a module with package variables. The var is declared in the module with use vars and resides in @EXPORT_OK as usual and one of the module subs checks the var to make decisions. When scripts use the module, the first sub call prints a menu and uses the var properly, but when calling other subs via the menu the var is somehow ignored: 

use Module;

$Module::configvar = 1;

print Module::menu(); # <- this works, configvar is set, but 
# not when invoking other subs from the options in menu().

The var is declared in the module but not defined. Some sub just asks if ($Module::configvar), which works, but only for the call to menu() made from the script. AFAIK the var is not being redefined anywhere in the module and it's not a persistent environment so... I'm stumped.

Hope this is enough information to spot my dumb mistake. I wrote a test module and script which worked as expected: the var was seen by other subs when invoked by the initially called sub. So I seem to know what I'm doing but dunno what's wrong with this module and can't post the actual code. Thanks for your consideration.
