I've been working on rigging a character for Torque, been in and out of the channel editor a lot, but suddenly whenever I go into it, Houdini freezes, even without a model up at all… I notice that the “End Frame” on the channel editor tab reads “1.4567e” which implies that it's a very small number (.000000014 etc…) and the start frame is 1, so it's trying to put up a backwards graph (I assume) is there any way to clear that setting in another viewport?

or at least delete the config

Nm… found the problem… in the hchanneleditor.pref file, the following got stored somehow

hRangeLower := 1.000000;
hRangeUpper := 146570367535334030000000000000000000.000000;
hRangeMaxLower := 1.000000;
hRangeMaxUpper := 146570367535334030000000000000000000.000000;

obviously that number probably shouldn't have been stored there

I just had the same problem as Visnarel
Deleting the file hchanneleditor.pref seems to have solved it
