I think it's related to combining the rotatations and translations, the rotation sliders will go back to 0 in some cases and I wasn't looking at the matrix values while adjusting the sliders so didn't realise there was still a rotation in effect.

I can't reproduce. I didn't see any difference with Slicer3.

What do you repeat at step 5 ? (the translation number change or the whole process change rotation, change translation).

Range -200/200 is a Slicer3 behavior, I guess it's been there for the purpose of going 180 degrees plus a bit more just in case. Do you confirm the need for a -180/180 range?

This seems to reproduce the problem:
Make a new transform, place a model under it in the Data module.
Move the LR rotation slider to -180.
Start to drag the IS translation slider. It slips out from under my mouse and moves in large increments. Let go of the slider and try to change the max slider range by highlighting the number in the box, pressing the backspace key, then typing 500. As I typed the 5, the max number set itself to 2700 or so. Highlighting the 2700 number, pressing backspace and trying to type 500 again, it jumps to 7000-something as soon as I type the 5. The max range adjusts itself to about twice the value that appears in the slider value box.
Trying to get the max slider range to reset takes a couple of rounds of highlight, delete, type, highlight, delete, type to get it to stick.

I can't reproduce on Windows 7 (Slicer 32bits Debug).
I'll try on a different machine. What machine do you have the issue? Can you try on a different machine ?

I'm seeing the issue on a debug build on linux 64, Fedora core 13.
Trying a windows 7 binary from the dashboard 2011-09-12 build), I don't see the same behaviour.

I can't reproduce neither on a Ubuntu 64b in Debug mode...

As reproduced on the tcon:

• start Slicer, go to the data module
• insert a transform
• go to the transforms module
• in global coordinate reference set the LR rotation to -180 (this might be the trigger)
• change to local coordinate reference
• grab the IS translation slider and it should jump out from under your mouse and the value increase/decrease a lot. If you try to double click and edit the value in the text entry box, it will not allow it.

Reproduceable on Slicer3

Since this does not seem happen often, moving to 4.4

The Identity button can get you out of this mode. Also if you want to flip and then operate locally you can harden the object first and then apply further edits.
