One of the changes we made in OrcaFlex 9.1 was a re-mapping of keyboard shortcuts. Mostly this was motivated by a desire to map CTRL+S to File | Save and CTRL+O to File | Open.
To make room for these changes we had to rearrange a number of other shortcuts. In particular the shortcuts to rotate the 3D View were changed to CTRL+ALT+ ← → ↑ ↓. Shortly after releasing version 9.1 we began to hear reports from some users that their laptop screen would suddenly be displayed upside down, or on its side, after using one of these shortcuts.
After a little detective work we have traced the issue to a piece of Intel software that is stealing these keyboard shortcuts before they reach OrcaFlex. The solution is as follows:
- Open the Control Panel and make sure it uses Classic View.
- Double click the Intel GMA Driver for mobile icon.
- Select the Hot Keys page.
- Deselect the “Enable Hot Keys” option.
This will fix the problem for Intel graphics cards, but there may be similar problems for cards from other manufacturers, or even for different Intel cards. I’m guessing that similar solutions will be available and that the steps described above should help you solve such problems.
