Therefore it would be very interesting with which application you copy a selected text to clipboard which can't be pasted into a text file in UltraEdit because it was copied only in CF_OEMTEXT.
This would be further interesting because Microsoft writes in same article
Microsoft wrote:The system implicitly converts data between certain clipboard formats: if a window requests data in a format that is not on the clipboard, the system converts an available format to the requested format. The system can convert data as indicated in the following table.
And the table below this information contains CF_OEMTEXT quite often. Therefore it should be no problem for any application pasting text available in clipboard only in format CF_OEMTEXT.
Also interesting is what MickRC3 posted (on first page of this topic). There could be a driver or a bad hardware which results in making a very small damage on copied data in RAM. I have had once a RAM with a stuck 0 in only 1 bit of the entire RAM. Everything else of RAM was okay. I needed a quite long time and damaged many files on this computer until I found this hardware problem, replaced the RAM and restored the damaged files from my second computer. When something is working just sometimes abnormal, then a hardware or software problem should be taken into account. Most bugs in software results always in same wrong behavior and then can be often easily found and fixed.
