Thank you Akash, but when I go back to library mode I loose what I see.
You may have a completely different workflow than I do, so my idea might not work in your case. I import my images and I work on them using Lightroom. Whenever I'm in Lightroom I'm either looking at my master images or images that were created by Photoshop when I have to go that route. If I need a copy to send to someone or to post on the Internet or to send to a photolab, I will export a copy suited for that purpose. Once I have used that copy for its intended purpose, it is deleted. In my opinion, there is no reason to keep "finished" copies of images. If you decide at some point in the future to make an adjustment to one of those images, you would have to remember to export another finished copy. And it just isn't worth the extra work and disk space to try to maintain extra copies, in my opinion.
Notice that you have put Develop into "proof preview" view for "soft proofing". If you don't know what it is, it's like a print preview where simulates how the photo will look when it is printed. The easy way to switch this off is with the S keyboard shortcut.
Also maybe mention which other program you are using to review the output. This may make a difference.
If you Right Click on the image in the Develop module you get an option to Export, Select that and adjust your export settings as you like then click the Export button. Do you get what you are seeing in the Develop module in the exported image?
"Save" isn't "Export" - Lr uses a fundamentally different workflow logic.
Anything you do to an image is "saved" (to Lr's database) in real time, without any user input - you don't need to tell Lr to "commit" what you've done to the image.
So "Export" is what - and only what - it sounds like. You really need to break this old way of thinking if you want to understand Lr properly.
As to accessing the Export dialogue from within Develop - Ctrl + Shift + E (on Windows) comes to the fingers so easily I don't even have to think about it - it's in my muscle memory, and is a lot faster than clicking buttons or accessing the Export option from the menu bar.

Export is a menu option in the Develop Module (File->Export). Export in the Develop Module is also, as pointed out by Keith, Ctrl-Shift-E.
But the most important thing Keith said is that Export and Save are not equivalent concepts. And specifically "You really need to break this old way of thinking if you want to understand Lr properly." You do not need to Export photos each time you are done editing them. In fact, I would say, you SHOULD NOT export photos when you are finished editing them, you should only export (or Publish) when you need to use the photos outside of Lightroom. If I shoot and edit 100 photos, and I want to make use of only eight of them outside of Lightroom, I only export those eight.
