Keyboard / Wacom Tablet Problems After Recent PS updates

I am having problems with the way my keyboard and Wacom tablet function in Photoshop after recent udates. This is under Windows 10, 64bit, PS version 24.6.

Keyboard: Keyboard doesn't sweitch functions in PS. Sometimes I have to press and hold the key or, else it reverts to the old function.

Example: I am in zoom mode (Z). I press H to switch to hand tool. It switches to hand tool momentarily and if I relase the H key, it reverts back to zoom! Or the other way. I am in hand tool mode and clciking z doesn't switch to zoom mode if I release the  Z key on my keyboard.

Sometimes, if I click H twice, it switches to H, sometimes not. I keep pressing H key on my keyboard and then somehow it switches to H.

Sometimes the problem disappears for a while but comes back some again.

Wacom tablet and pen: The hand tool does not want to release the image. I am zoomed into the image and use hand tool to navigate. In the past, I could simply hover and click to diassociate the image motion from the pen's movement. Now, it persists on holding onto the image and moving within it.

Scrubby Zoom: The option has completely disappeared. It is not gray-put. It is simply not there any more.

Anyone having any idea what's going on here?

Thanks.
