I had a similar issue. So incase it comes up again, (and you may have already done this) but I fixed it by going to file>options>window settings> then checking, or un-checking, the "Display as separate window" box.
I'm curious, did you try this?
I'm scared to try it since I got it fixed, but now I'm curious in case I need to seperate it sometime.
I thought I remembered some super secret handshake and chant to make it work!
ha ha yes it should work. I really recomend the floating model tree; makes my screen seem bigger. with that you can now see both your layer/drawing tree and model tree at the same time.
Also I created a mapkey to open and close the tree.
mapkey x @MAPKEY_NAMEHIDE TREE;@MAPKEY_LABELHIDE TREE;\
mapkey(continued) ~ Command `ProCmdEnvModelTree` 0;
if none of that works, that means you're doing the handshake wrong.
don't you still have the browser docked taking up space? that's why i've never found it useful since the browser takes up the same amount of space.
Yes it is.
My solution was creating a mapkey. Then, using one of the three auxiliary buttons on my mouse (I'm not sure what they are really called but auxiliary sounds like it should work) I assigned that button to the key stroke that runs my map key.
With one hand on the keyboard and the other on the mouse with extra buttons I can toggle the model tree and my layer/ drawing tree very quickly.
I Know this is just a preference thing but I think it's a great
