Unsettling results of benchmarking XDM on a slow machine. Is it really that bad?

The Windows download for J.A.C.K. on the official site just downloads an HTML file, not the actual program.

JACK freezes for a few seconds every time I try to select a group of objects on the grid. How do I fix this?

Is there a way to turn off the autosave a new .jmf feature and make it actually save the map?

Hello, I love the JACK editor and have been using it constantly to work on my mod Occult-Scrim for HL1.

Is it possible to toggle a different kind of SPRITE selection? Often.. if sprite scale is set big - the sprites prevent you from easily selecting things around it. My usual process in 3D view is to keep clicking on sprites and pressing H to quick hide them until I get to my desired selection.

Puu.sh

I was able to configure the FGD for lot of entities to use my custom models.
However I was not able to get env_sprite to use my "sprite helper" model

Puu.sh

I am able to use sprite helper models for env_sprite in hammer editor for source engine and it greatly helps working with sprites I believe.

Thank you for this great program !!! ; ) I also noticed Paste Special seems to do nothing if you use keyboard ENTER to press OK or if you don't wait about 1 second after the dialog window comes up.

Steam version needs update, and there is a bug that makes app does not close properly- every crash or exit on demand will make Steam thinks that JACK is still running- you can't exit steam or relaunch the app. Pleae consider fixing it, it works like this for over a year!

I also have this problem. My current solution is to have a .bat file to kill steam before I try to run jack again
