Is that when typing on toplevel text or inside insets?

Hi,
I can confirm this slowness. I installed LyX 1.4 from the binary
installer on a MacBook Pro (Intel processor) so LyX is running in a
processor emulation called Rosetta. This amplifies the sluggishness,
which is bad for me but good for seeing directly where LyX is being
slowed down. E.g., when I use arrow keys to move into a math formula,
then I can press the down arrow multiple times until LyX finally
moves out of the equation again. The buffered arrow key events then
cause the cursor to slip a couple of lines down before LyX comes to a
halt. The worst slow-down appears when the cursor happens to be in a
sub-level of a math formula, such as a subscript. It can take about
one second to get out of a formula environment (which is an
unacceptably long time when you're in the flow of typing).
Another issue is that the scroll bar on the LyX window doesn't seem
to work properly. Clicking on areas that usually create a page-down,
I just get a line-by-line scrolling behavior.
Finally, my issues with screen fonts for special math symbols such as
\iiint are still unresolved (bugzilla bug 2326) in 1.4 binary.
Regards,
Jens
