Text is deleted when trying to place the cursor (magnifying glass) I am having a hard time finding documentation on this behavior. The negative response received from this user on everythingiCafe makes me think that this is a bug. Basically, what happens is:

When you have a string of text that overflows behind the visible input box, or have a string of text which wraps inside the input box, if you move the text cursor around (using the magnifying glass), sometimes the text before the cursor will start to be deleted if you continue to hold the cursor.

It is worth noting that this rate of deleting characters is much faster than holding down the Delete key.

Has anyone else experienced this? Is it a bug? If not, what are the conditions which trigger this unintuitive method of deleting text?

I am using an iPhone 4 (MD146LL) and have experienced this with iOS versions 5.0, 5.0.1, and 5.1.
I have never observed such behaviour.

It is a bug.

Selecting text is not supposed to delete text.
