thanx for the suggestions thus far.
ok, I went to Tools > Customize and selected the Setup tab. The current “Load From” source was “autocad.” I clicked the dropdown arrow and selected tcv6_1024x768, and with “Load all selections” checked, I clicked the “Load From:” button. A pop-up with the message “Are you sure you want to reset this? This action will remove all settings.” I clicked yes, watched the drawing refresh then clicked “Close.”
I then clicked the line draw tool and tried the space bar. It did not return to the select tool. I went back to the one working instance I still have up and verified that it still does respond to the space bar.
I repeated the above incantation, this time clicking the “Reset all” button instead of “Close.” Still no luck.
Everything was working ok up until last week when I inadvertently mistyped something that made the intrinsic “space bar -> select tool” shortcut stop working on that and any new instances of TurboCAD. It would be nice to know what command my mistype issued to TurboCAD and how to reverse that process. Short of that, I’d be happy to program in a custom keyboard shortcut that associates the space bar with the select tool - if I could figure out how to assign keyboard shortcuts.
any other ideas? g_k
by the way, running multiple instances hasn’t caused problems thus far, and considering that one of them I left running still works, I don’t think that has anything to do with why space bar stopped working.
