Incorrect cooperation with Edit Plus on new versions

Since I have installed new version WinSCP 5.17.10 I have problem to edit files with my EditPlus4.3 build 2583. I am using it by clicking on file in remote files window, and file opens in the editor. It enables saving button which saves via WinSCP, but since the last version time when it works properly dramatically has been shorted. Moreover WinSCP has been starting to save enormously large portion of data as it shown on the display.
What to do?
I am trying to use one of the previous versions of WinSCP.

Sorry, I do not understand what you mean by "properly dramatically has been shorted". Please explain.

Regarding "has been starting to save enormously large portion of data as it shown on the display": Portion of what data? WinSCP uploads the whole saved file. It does not upload any portions.

When SCP disconnects becouse of timeout (very shortly) its not easy to become connected. SCP freezes for not short time. In previous versions it automatically refreshes and go online automatically continuing transfering. It was also strong problem in cooperation with Edit plus as mentioned previously.

Now WinSCP cannot connect to my server which is working properly. I can connect by Putty SSH and use WWW pages and MySQL database.
Where is a problem?

Can you connect with any other SFTP client? If you can, post its log file and WinSCP session log.

Sorry, I do not understand how do the two WinSCP logs respond to my earlier post.
