GWT disable text selection in an HTMLTable

While modifying FlexTable to handle cell selection It took me a while to figure out how to disable the native text selection behavior of the browsers on 'SHIFT+Click' events. Turns out this native javascript function does the job pretty well. I tried playing with event.preventDefault() and event.stopPropagation() but that didn't work.

private native static void disableTextSelectInternal(Element e, boolean disable)/*-{
if (disable) {
e.ondrag = function () { return false; };
e.onselectstart = function () { return false; };"none"
} else {
e.ondrag = null;
e.onselectstart = null;"text"

public void onKeyDown(KeyDownEvent event) {
if (event.isShiftKeyDown()) {
disableTextSelectInternal(table.getElement(), true);

How to disable GZIP compression in Firefox

Not sure this is the only/best way but I used the following steps to disable gzip compression in Firefox 3.0:

  1. Type about:config in the URL bar (Accept the disclaimer)
  2. Type encoding in the filter field underneath the URL bar
  3. Doubleclick the line network.http.accept-encoding
  4. Enter the following value instead of the default: gzip;q=0,deflate;q=0
Note: See comment from Anonymous below for a possible better way of doing this. Thanks Anonymous!

Delete Flash9f.ocx - Access is denied

After installing Windows 7 on an XP partition I couldn't completely get rid of the Windows.old folder. The culprits were a few ocx and dll files left with strange permissions by Adobe Flash and Acrobat. All attempts to take ownership and delete failed.

I was finally able to delete these files easily thanks to Unlocker.
