default scroll bar and text issues, please help!

[calibachrome]

i've tweeked my phone out and I'm pretty happy aside from two things.
1st the default scroll bar is changed when u install bsb tweaks.
how can i get the default scroll bar back without doing a hard reset?
2nd i'm having issues when replying to a text, as I'm typing the screen jumps up to the
messenger and the message I'm replying to. and yes u can still continue typing, but what
u are typing freezes until u tap the screen again and then what you were typing shows up
which is very annoying considering this is the smartest smart phone. didn't have this issue with my tp2. any help would be greatly appreciated!
