Texmaker and TeXstudio ⇒ TeXstudio | Editing Text is overwritten instead of moved

[Rustam]

I am working in TeXstudio and when I push the space bar the word after cursor is erased and not moved. How I can correct this?

Shouldn't behave that way. Did you check "Ins" key on your keyboard. If it's active, then what you described is completely normal behaviour in any editor.
