Hi again!
Firstly, in regards to the fishing through the zips, I've almost got the
script for that ready- I should have mentioned it, but I wasn't sure if you
were still here. I'll post it as soon as I finish it.
As for your computer woes, they are unfortunately common in switching OSes.
However, there appears to be hope for resolving them.
I'm reasonably certain sounds carrying between pages in the browser is normal
functionality. There's likely a setting to stop it happening, if that's the
case- I'll get back to you unless somebody else can be of more assistance.
The problem with pausing the video not stopping sound, the keyboard randomly
freezing, (maybe) the tabs not showing up, and the browser sometimes locking
because of high CPU usage are possibly signs of a slow computer. Do you know
how much RAM you have and what processor you're using- you can find them
under 'Details' in system settings if necessary.
The built in mouse (I presume a touchpad) not working could be one of several
things. Is it completely unusable, not clickable but movable, or just a pain
to use?
For the pages randomly jumping to the top, I can't say I have a clue. There
might be a trigger, such as touching the mouse (to scroll down, or just be
accident) or rubbing an arm/hand on the keyboard. If not, then I honestly
don't know.
