Q: Safari 5.1.5 not working with Google Docs

In a Google text doc, there is a problem with line spacing such that all the lines in the doc are stacked up on the first line making it unreadable and unusable. I've had this problem with the last few releases of Safari but the problem has just become worse.

If I click anywhere in the body of the doc I get:

     Google Docs error

     This error has been reported to Google and we'll look into it as soon as possible.

     Please try one of these interim solutions:

• Reload this page.
• Download the document by right-clicking on it in the main document list and selecting "Export."

    ...

I'm running Safari in 64-bit so that's not the problem and switching back to 32-bit doesn't fix it.

I can view the original format of the doc with proper line spacing by selecing File > See original, but can't edit the doc at all.

Anybody come across a solution or work-around for this?

Thanks,

Paul
