Small editor quirks between 5.0.1 and 5.1.2

When I upgraded to 5.1.2 from 5.0.1,  I had a few annoying items show up.

For example,
In 5.0.1 a backspace when the cursor was in column 1, would delete the 
line and move the cursor the last column of the line above.
In 5.1.2 a backspace in column 1 does nothing.

In 5.0.1 when the cursor was in column 1 of a line, CTRL-End would select 
entire line and the DELETE key would blank the line
In 5.1.2 CTRL-End still selects the entire line, but the DELETE key does 
nothing.

In 5.0.1 when I was editing an RPGLE source member and I typed %, or % and 
the beginning of a BIF, the pop-up box of BIF's would come up.
In 5.1.2, I have to do a CTRL-Space to get the pop-up window.

I assume that this was a setting in the LPEX editor preferences, but I 
haven't found it yet.

Any suggestions?

Thanks!
