[GRASS-dev] TclTk question for Windows

[Michael Barton]

Below is a query from Paul Shapley about NVIZ and TclTk in Windows. 

Is TclTk a separate installation for Windows folks or is it bundled with GRASS? If the latter, what version is bundled? I'm using TclTk 8.5.7 and it works fine. I've heard that 8.6 doesn't work, but maybe that is only a Mac problem.

> Just checked with an older version of Grass (6.4.0RC5 on Mac OSX with TclTk/Wish) and the same data displays at full (very detailed) resolution. Just wondering, does the windows version need TclTk installed separately?. I'm using the highest possible display resolution on 6.4.0RC5 on mac and 6.4.2RC2 on windows (same settings but low resolution is all i can get on windows). Setting '1' highest res does not work for me in the latest release.
