So im on my MacBook, i try to open an application on the dock and then an error with the logo of the app comes up saying "Application could not be opened due to error -10810". So then i tried opening other apps on my dock no luck, same error, then i tried opening through my Applications folder same thing. All my currently opened apps work fine, but if i quit them and try to reopen them the error comes up. So i restarted, all was fine after that, i could open and close and reopen apps fine, but after 3-4 hours i come back and then i try to open apps and the thing error comes back! i restarted 2-3 times but it still comes back after some time!! My specs are MacBook 1.83 GHz Intel Core Duo 1.5 gb ram running Mac OS X 10.5.4... I don't want to reinstall leopard!
