I'm using phpstorm 7 (trial) on windows 8.
I use file watchers for sass/scss to css compilation. However, the file watcher seems to kick in at times while I'm still typing a css rule and doesn't always detect a file change when I'm done typing. This often leaves me up with an error as css output (because it did the compilation when there was an incomplete css rule). Then I start adding or removing blank lines, hoping the file watcher will pick up a change, but most of the time it doesn't.
I don't know if this is a windows file system or phpstorm problem, but it is very very annoying. One solution would be an easily accessible button or context-menu item to manually (re)start the compilation.
