Closing pop up frames with Selenium IDE - testing

Question

I am using Selenium IDE for some tests. But hardly stuck with one action - i need to close a download pop up window in FF.
Common way to perform this would be using selectWindow command, BUT - my pop up - it's actually a frame, so it does not have an ID and other useful parameters for IDE.
All my attempts to close this pop up lead to closing main window.
I tried something like this, but did not work either:
<tr>
<td>click</td>
<td>css=#fpm > img</td>
<td></td>
</tr>
<tr>
<td>waitForFrameToLoad</td>
<td>http://www.somesite.com/lg/c.do?proj=1111&aid=1111&rnd=0.132456</td>
<td></td>
</tr>
<tr>
<td>pause</td>
<td>5000</td>
<td></td>
</tr>
<tr>
<td>close</td>
<td></td>
<td></td>
</tr>
<tr>
Is anybody faced this problem in the past? I know, that JS can be used at this point, but i don't have any clue how. Can you advise?

Finally, i found a way...
Bit tricky, but it works. So, this was an IDE bug, where IDE is unable to identify opened "_blank" windows. Here is workaround:
<tr>
<td>storeAttribute</td>
<td>//a[#'Here you can use id/class/href/rel link, etc, for ex: #rel='Register']/#href</td>
<td>href</td>
</tr>
<tr>
<td>openWindow</td>
<td>${href}</td>
<td></td>
</tr>
<tr>
<td>pause</td>
<td>2000</td>
<td></td>
</tr>
<tr>
<td>storeEval</td>
<td>selenium.getAllWindowNames()[1];</td> -- [1] - window to select from array of window names, 0 - it's a main, 1 - 1st opened pop up, 2 - 2nd, etc.
<td>windowName</td>
</tr>
<tr>
<td>pause</td>
<td>2000</td>
<td></td>
</tr>
<tr>
<td>selectWindow</td>
<td>${windowName}</td>
<td></td>
</tr>
<tr>
<td>verifyElementPresent</td>
<td>Verify something here</td>
<td></td>
</tr>
<tr>
<td>close</td> -- close pop up
<td></td>
<td></td>
</tr>
<tr>
<td>selectWindow</td> -- return to main window
<td>null</td>
<td></td>
</tr>
