As reportedby Jonas B on dev list:
whenever i dragg the map around, the googleLayer disappears after like an inch or two of movement – and stays invisible as long as i keep moving the mouse. once i stop, even for a brief moment, the layer correctly loads. all other layers i tried to put atop the googleLayer show fine even when the googleLayer doesn’t. if i don’t stop moving the mouse the googleLayer just stays gone. this happened when using the official examples, and all demos i made trying to get it working. played around with different versions of OL, but it seemed to work in none of them. tried it in ie 7 and ff2/win & ff2/unix. maybe this already has been spoken about, but i could not find any posts regarding this.
the whole googleLayer disappears all tiles at once, nevermind which kind of googleLayer (satellite/map/hybrid) i use. it seems to disappear around the moment when some new tiles should be loaded. anybody ran into that one too? i feel this is quite inconvenient, it just ruins the fun when browsing with a googleLayer in my map. im not into google, but it would make my work a lot easier , and better looking =).
