Word 2013 crashes when deleting an equation

Whoops, had a typo, <alt enter> should be <alt => (meaning, pressing alt and the equals button at the same time). The key sequence to make it crash is:

a <alt => m i n ( <backspace> <backspace> <backspace> <backspace><backspace> <backspace>

Assuming that I interpreted your instructions correctly so that before pressing the backspace key, I have

in the document, then pressing the backspace key 6 times, leaves just the "a" in the document and Word does not crash.

Here's what it looks like for me:

It looks you you did type it the same way I did. Are you using Word 2013? Your equation editor is blue, while mine is gray.

I did try it in both 2010 and 2013, the latter on a Samsung Slate.  For convenience, the screen shot was taken in Word 2010 simply because it is on that computer that I respond to questions in the forums.

In 2013, the appearance is identical to your screen shot with hardly any of the letter a being visible.

Sorry for being persistent; this bug is pretty annoying.

I reproduced this bug on three seperate computers, two which were running Windows 8.1, and one which was running Windows Server 2008 R2. When I type up to the open parenthesis, I get:

Note, even though a space appears between the 'n' and '(', I didn't type it (Word inserts it automatically). Next, after pressing <backspace> 5 times, I get this:

which is an empty equation box. If I type <backspace> again, Word crashes.

If I switch to use Overtype mode, as shown in this screenshot:

Then, after pressing typing the 'a' and the equation, then pressing backspace 5 times, I get the following instead:

In this case, Word doesn't crash after pressing backspace, but instead deletes the equation. It seems that I shouldn't be able to get an empty equation box, but instead should always get "Type equation here." Without overtype mode, I just get an empty equation box though, which crashes when I press backspace inside of it. Perhaps other settings also affect it - with the default Word settings, it will crash.

I recently faced this problem. Very annoying, in particular for people who use equations a lot. Really appreciate if it is fixed.

Can it have something to do with recent updates (for Sweden)? It never happened to me before (e.g., in 2014) although I use equations quite frequently.
