BT MPower 32 running Ks 7.5 build 29 (problem either never or not significantly present on classic running ks 7.2)

When spacing between words, the bn will with some frequency combine the space character with the last non-space character entered and treat that combination as a chorded command. After the t-h-e sign for the word "the", for example, I can easily find myself typing in the format menu. When a word ends with the letter e, typing the following space will exit the file. And so on. There are parts of Keysoft which I probably would never have visited, except that an unwanted chording of keystrokes intended as a character followed by a space took me there.

The problem is worse the faster I type, which makes me think there's a timing issue, or some feature of the hardware or software which blurs the boundaries between characters being entered. If my typing were just sloppy (which happens some times), I'd get the wrong character, characters run together without a space in between, or missing characters.

The problem is particularly bad when the last character of a word is a braille contraction such as i-n-g, b-l-e, etc. After such characters, I have to wait even longer than usual in order to prevent the occurrence of an unwanted chording of that last character with the following space. This means that typing has to be a bit choppy and that I have to think more about the actual entry of the material than I would have to without this problem. I imagine that the cause of the problem in this situation is that Keysoft is back translating on the fly and needs time to look up the symbol in some table, back translate it then store the result before it's ready for more input. If that's what's going on, I wonder if the problem couldn't be fixed by buffering the translation process so that translation could catch up with entry when, for example, I pause between sentences or paragraphs. Alternatively, I'd like a way to turn off the automatic back translation and, if it has to be done at all, let it be done when the file is saved. If the file is to be a Grade II file anyway, why back translate at all, unless told to do so through the file-translate menu? If it's not back translation that's causing the problem, what is it, and how do I fix it?

Hw tech support tells me the only thing I can do is to type more slowly . But that approach makes me risk falling behind in meetings or lectures. It also reduces overall productivity when drafting documents from wat it could be if these problems did not exist. For the price of the bn, and given its mission to enable braille users to be productive in a medium which is hospitable to their skills, features which slow down braile entry and which lose data when entry is too fast seem particularly unwelcome.

Thanks in advance for any suggestions.

BTW: The problems described above happen both on battery and when connected to power. The flash disk reports 56.9 mb free, so I'll be surprised if overcrowding is the issue.
