Changing the CURSOR with JSFX Collapsible Blocks - help with css

hello, i have recently installed jsfx module and it works fine, but i was wondering about this :
well the collapsible blocks are already there, the module does its work, but it fails in a manner of speaking
when the user moves the mouse over the block's title, he just gets a text cursor, so he probably ignores the block...
so i want to display a hand cursor(for example) over the collapsible titles or over all the blocks titles(at worst), i have seen the support request on the module's page but i couldn't figure out how to implement the additions
here's the code that the module's maintainer provided

#leftColumn .blockTop h3 {
background:transparent url(icons/up.png) no-repeat scroll left center;
}
#leftColumn .blockTopOpen h3 {
background:transparent url(icons/down.png) no-repeat scroll left center;
}

so i created in icons folder in my themes folder and dumbly added two icons named up.png and down.png (yeah i didn't even rename them) then added the code to my theme's css file, deleted my browser's cache, refershed and hoped for the best but nothing changed

here you should take note that i am using drupal 5.7 and a lightly modified version of the bluemarine theme...

now what i am asking for is just the CURSOR thingie, and optionally the icons...

wating for any code you provide, thanks in advance...
