debugging - PHPStorm v.5 issues -

i use phpstorm 5.0.2 debugging php/mysql projects wamp framework (php 5.3.1, apache 2.2.9, mysql 5.5.24 on windows 7 platform).

question 1: times in project, when watch debug variables used, take seconds refresh on debug panel, after each code step. each watch variable takes few seconds refresh, more watches have been defined, more slowing down takes place during code stepping, rendering debugging disappointedly slow. so, example, cannot press 'step over' every second, because have wait till watch values refreshed, before press next 'step over' , may take 5 or more seconds.

this didn't use happen before, started happening lately , doesn't happen time. when doesn't happen, code stepping can advance quickly, did.

in project have set quite few breakpoints, wondering if culprit. tried disable of them (not delete them, since need keep them future use), didn't see improvement.

i tried different xdebug versions, no change took place.

i have tried switch browsers, delete browser data (cache, etc), restart wamp server, browser, phpstorm, windows, many times issue remains. other times, disappears little while , reappears later in code.

i wondering reasons might produce slow refresh.

question 2: there way export or save breakpoints project?

question 3: if tried phpstorm 7, in case slow-refresh issue disappeared, open phpstorm 5 project in order not loose breakpoints have set?
