I am using Photoshop Extended CS6. A new problem has started to occur recently. I can select a tool, but I can't change the tool type. For example, I can select the Lasso Tool and when I right-click the tool fly-out appears, but I cannot select a tool from the fly-out to change the tool type. The editing tools, at least the ones I can select, still work except for the selection and crop tools. For the crop tool, the crop lines appear at the edge of the image but they cannot be moved. For the selection tools, nothing is selected. I can still use menu commands such as Canvas Size.
This happens when I open a file or start a new file. I have Windows 7, 4G memory and nothing else running. I have tried 32-bt and 64-bit versions.
This has happened intermittently for a month or two. In the past, freeing up space on a hard drive seemed to help. But now I have 50G free on one drive and 30G free on another so I don't see how that could be the problem. Rebooting allows me to use the crop tool once, but then the problem reoccurs.
Are Photoshop and OS fully updated and have you performed the usual trouble-shooting routines (trashing prefs by keeping command-alt-shift/ctrl-alt-shift pressed while starting Photoshop after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved and making a note of the Preferences you’ve changed, 3rd party plug-ins deactivation, system maintenance, cleaning caches, font validation, etc.)?
My computer is a Dell Studio 1747. I ran Dell's system diagnostic and everything passed. I thought it might be a stuck key, so I removed the internal keyboard and connected a USB keyboard. No change.
While testing the keyboard, I figured out the exact action that causes the problem to occur. When I start Photoshop, it works correctly until I use the keyboard for anything or switch to another open application (using the mouse). Then the problem occurs and stays until I restart Photoshop. This happens using the internal keyboard or with the internal keyboard removed and using a USB keyboard. An example: I use the Rectangle Selection tool to select an area. This works repeatedly. Then I press and release the Shift key. Then I try to select an area. The problem occurs and the tool no longer works and stays that way until I restart Photoshop.
Do you have any kind of keyboard mapping program? Perhaps wrong term but one where you execute a set of keystrokes and it remembers it?
You should have 10 to 20% free disk space on each of the hard drives.
Have you run malware/virus scan? Maybe a keylogger program?
No keyboard macro programs installed. Microsoft Security Essentials is installed. It says it is up to date and there are no problems. A keyboard test program found no problems. I have tried two USB keyboards with the same results I have 10% free on my system drive: and 15% free on my second drive.
